I identify with this so much, and it's why I'm on OKCupid to begin with. I feel like there's a lot to say, though I don't wanna, you know, order you around or whatever.
I guess first off: do you have a friend? A good friend? Don't feel like shit if you don't, it makes sense - when it's a fucking struggle to get out and handle errands, well, it's hard. But if you do: ask them to write part of your profile. It helped me so much - I have a profile that feels so damn normal and confident, yet honest. You're stuck in your headspace - getting those first words written by a person who knows and likes you will help distance you.
I feel this might be most important: DO NOT FORGET THAT THIS IS ABOUT YOU. The words "ah, fuck it" are completely invaluable right now. You made a profile. Fuck it - that is an accomplishment in itself, especially that you did it in a way that felt honest. Being kind to yourself isn't as dishonest as it feels, but whatever, moving on.
Also, remember that to a lot of people, you are basically a piece of meat to briefly pan over and forget. Yes, there are ways to improve it (if you haven't answered 400 questions yet, try it), but you're basically just another person in a list. There is no possible way you are going to do "well." I've been getting about 4 likes a week, and according to this subreddit, that's a lot for a guy. It really does not feel like it - I feel worse, in fact. But fuck it.
Again, this is about you. And yeah, gender/sex does matter a bit in the ratios as sad as it is. But don't see this as "how many of these people would like you," see it as expressing interest in these people - you're giving them a chance. There's a lot of horndog dudes on the- well, Earth, I guess. Being genuine and non-creepy as a stranger is hard. I open conversations as if I'm interviewing them about why they caught my eye: "Hey there! Man, what is teaching like? That sounds incredibly cool, but I honestly don't think I'd manage, kids are rough sometimes. Is it ever draining?"
Chances are, she won't answer, because she'll - well, there's a ton of reasons, but the main one is probably that she'll be scrolling past multiple messages. Don't bother trying to catch someone's eye, just begin a conversation that you'd enjoy, were it to continue.
Also, that lady you're about to meet up with? She has things she hasn't mentioned, either.
Oh, and for the record: web design is a skill. Trust me. Unfortunately, you and I have a bad skillset for a self-doubter, because it's a skill that's hard to monetize right now, since people are generally clueless about the actual work involved. You are skilled.
